Nigella’s Courgette and Lime Cake is a delightful combination of grated courgettes and lime zest, creating a soft and moist cake with a hint of citrus. The courgettes add a lovely texture and moisture, while the lime gives the cake a refreshing and slightly tangy flavor. Typically, the cake is topped with a lime-infused cream cheese frosting, enhancing its flavor and adding a touch of richness.
